Simulating a quasiparticle on a quantum device
Rimika Jaiswal, Izabella Lovas, Leon Balents
We propose a variational approach to explore quasiparticle excitations in interacting quantum many-body systems, motivated by the potential in leveraging near-term noisy intermedia…
Non-equilibrium time evolution in the sine-Gordon model revisited
Dávid Szász-Schagrin, Izabella Lovas, Gábor Takács
We study the non-equilibrium dynamics of the quantum sine-Gordon model describing a pair of Josephson-coupled one-dimensional bosonic quasi-condensates. Motivated by experimentally…
Exact Solution for the Transverse Field Sherrington-Kirkpatrick Spin Glass Model with Continuous-Time Quantum Monte Carlo Method
Annamária Kiss, Gergely Zaránd, Izabella Lovas
We construct the first complete exact numerical solution of a mean field quantum spin glass model, the transverse field Sherrington-Kirkpatrick model, by implementing a continuous-…
Excitations of quantum Ising chain CoNb2O6 in low transverse field: quantitative description of bound states stabilized by off-diagonal exchange and applied field
Leonie Woodland, Izabella Lovas, M. Telling +3
We present experimental and theoretical evidence of novel bound state formation in the low transverse field ordered phase of the quasi-one-dimensional Ising-like material CoNbO…
Quantum Coding Transitions in the Presence of Boundary Dissipation
Izabella Lovas, Utkarsh Agrawal, Sagar Vijay
We investigate phase transitions in the encoding of quantum information in a quantum many-body system due to the competing effects of unitary scrambling and boundary dissipation. S…
Detecting and stabilizing measurement-induced symmetry-protected topological phases in generalized cluster models
Raúl Morral-Yepes, Frank Pollmann, Izabella Lovas
We study measurement-induced symmetry-protected topological (SPT) order in a wide class of quantum random circuit models by combining calculations within the stabilizer formalism w…
